Finite element modal analysis of the rolling mill hydraulic servo-cylinder testing system load frame

The load frame is a part of important equipment of the AGC rolling mill hydraulic servo-cylinder testing system.The frame is used to load and assemble the hydraulic servo-cylinder as well as some other component.The frame is supposed to make no effect to the testing result in the dynamic test of the rolling mill hydraulic servo-cylinder testing.The load frame is analyzed base on finite-element method in this paper.After the model of the closed-type frame is built,the top 8 bands of the vibration modes and natural frequencies are obtained in the modal analysis research on the frame through the software ANSYS,and it is known that the resonance vibration of the frame will not occur under the dynamic test frequency of the test system.
